1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Sex chromosomes have independently evolved in various species, displaying unique evolutionary patterns, including differentiation, degeneration, and repetitive DNA accumulation. Pentatomidae hemipterans are characterized by a highly conserved diploid number of 2n = 14 with a XX/XY sex chromosome system, i.e. 2n = 14, 12 A + XY. Thus, it represents an interesting group for investigating the reorganization of repeats in conserved karyotypes, i.e. the absence of large chromosomal rearrangements. Using comparative genomic hybridization (CGH) with male and female genomic DNAs (gDNA), this study examined a total of 25 Pentatomidae species to uncover repetitive DNA dynamics and their role in chromosome differentiation, especially sex chromosome differentiation. New karyotype data for nine species reinforces the chromosomal stasis in Pentatomidae for macro-chromosomal structure. However, significant variability in repetitive DNA patterns on autosomes and sex chromosomes has been revealed despite the karyotypic conservation. Autosomal signals varied in intensity and distribution, with some species exhibiting terminal enrichment of repeats, while others displayed dispersed patterns. Sex chromosomes showed distinct hybridization patterns, with the Y chromosome exhibiting more significant variability compared to the X. These findings emphasize the dynamic nature of sex chromosomes and suggest further studies combining genomic sequencing and cytogenetics to uncover sequences and the mechanisms behind their evolution.
